Description
Discussed in #546 where I've written an alternative to tuple_combinations, array_combinations which is an iterator that outputs [T; N]. This feature requires const generics which were introduced in Rust 1.51. It was suggested that we can bump the MSRV in a major release (ie itertools 0.11) but it would be sensible to add more features along side.
This crate uses a lot of tuples where arrays make more sense. Tuples are good when you have multiple types (eg cartesian product or zip) but when you have a collection of the same type, a slice/vec/array makes more sense.
Here's a list of functions that seem to qualify using arrays:
- circular_tuple_windows -> circular_array_windows
- tuples -> arrays
- collect_tuple -> collect_array
- next_tuple -> next_array
These all work on a single iterator over the single I::Item type, and since these use tuples, the number of elements is known at compile time, making them perfect for using arrays instead of tuples.
